eclipse快速创建一个Spring Boot应用

1，创建一个空的maven项目

2，添加parent

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.2.RELEASE</version>
    </parent>
    

3，添加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

4，添加编译插件

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

5，添加启动类

package com.googosoft.hystrix;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HystrixApplication
{
    public static void main( String[] args )
    {
        SpringApplication.run(HystrixApplication.class, args);
    }
}

6，添加测试Controller

package com.googosoft.hystrix;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/** 
* @author songyan 
* @version 2020年2月11日 上午10:37:44 
* @desc
*/
@RestController
public class TestController {

    @RequestMapping("test")
    public Object test(){
        return 22;
    }
}

7，重新制定jdk版本

8，完整pom

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </parent>

    <groupId>com.googosoft</groupId>
